During your Live Video, your viewers can give you diamonds. You can also give away diamonds to show your appreciation to other streamers. To see how many diamonds you have already collected, click on the profile icon in the top left corner of the app. Now you can see the number of received diamonds below your credits. You have the opportunity to redeem your diamonds in the form of a cash or credit reward. Cash reward means that you can cash out the collected diamonds as money. If you choose the credit reward, you can convert your diamonds into credits and use them to make gifts in other Live Videos.
